Starrett 65632 Hole Saw 3-1/4 in Carbide Tipped

Product Description

The STARRETT 65632 is a carbide-tipped hole saw designed for cutting clean, accurate holes through hard and abrasive materials. With a 3-1/4 inch saw diameter and a 1-5/8 inch cutting depth, it handles a wide range of trade applications where standard bi-metal saws wear out prematurely. The toothed cutting edge and constant pitch pattern provide consistent chip clearance and reduce binding during the cut. This saw is built without an integrated arbor, so it pairs with a separately sourced arbor sized for 3-inch pipe tap compatibility. It is a practical choice for HVAC, plumbing, and construction trades cutting through tough substrates on the job site.

The STARRETT 65632 is suited for cutting fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring materials. HVAC technicians use it when penetrating fiberglass duct board or masonry walls for duct and pipe pass-throughs. Plumbers rely on it for cutting through plaster and MDF flooring panels during rough-in work. Its carbide-tipped construction holds an edge longer than standard steel saws when working repeatedly through abrasive or laminated materials, reducing the need for frequent tool changes on multi-penetration jobs.

Key Features

• Carbide-tipped cutting edge for extended life in abrasive materials
• 3-1/4 inch saw diameter suitable for standard pipe and duct penetrations
• 1-5/8 inch cutting depth handles typical wall, floor, and ceiling assemblies
• Toothed edge with constant pitch pattern for consistent chip clearance
• Non-arbored design allows use with a compatible separately sourced arbor
• Rated for fiberglass, masonry brick, MDF, plaster, Formica, and suspended floor materials

Compatibility

Designed for use with materials including fiberglass, Formica, masonry brick, MDF, plaster, and suspended flooring. Compatible with arbors sized for 3-inch pipe tap applications. Arbor is sold separately and is not included with this saw.

Installation Notes

Install the hole saw onto a compatible arbor before use and confirm the arbor is fully seated and secured. Always wear eye protection and a dust mask when cutting masonry, fiberglass, or MDF, as these materials produce fine particulate. When cutting into walls or floors, verify the location is clear of live electrical wiring, plumbing, or structural members before beginning the cut. Operate at a drill speed appropriate for the material being cut to avoid overheating the carbide tips.
